Hydrogeology and origin of waters of the Panyam Volcanic Line springs, Jos Plateau, Nigeria

The PVL springs are used for both domestic and agricultural purposes. seepage from the has resulted in producing a large expanse of wetlands is therefore intensively use dry season farming. aim this study was to determine hydrogeological, hydrochemical characteristics, origin their suitability irrigation. hydrogeology determined by field mapping. physico-chemical parameters were laboratory methods. For cation anion analysis ICP-MS wet methods employed respectively. stable isotope composition oxygen (δ18O) hydrogen (δ2H) analyzed Isotope Ratio Mass Spectrometer. revealed that waters generally neutral with an average pH value 7.3. TDS EC values 127.8mg/l 246µs/cm These fall within fresh water class. Mg2+,Ca2+, Na+ K+ concentration 16.3mg/l, 15.8mg/l, 10.8mg/l 5.58mg/l anions HCO3-, SO4 Cl- 140mg/l, 8.6mg/l 3.4mg/l Piper trilinear diagram show spring predominantly Mg-Ca-HCO3 type potable qualities based on WHO drinking standards. sodium Adsorption (SAR) Sodium Soluble Percentage (SSP) range between 0.44 0.84 26.4 54% respectively falls irrigation quality Stable compositions δ18O δ2H ranges -3.60/00 -4.90/00 -200/00 -280/00 meteoric composition. This further affirmed versus plot correlation Standard Meteoric Water Line.
